Effective approach to the problem of time: general features and examples

Martin Bojowald, Philipp A Hoehn, Artur Tsobanjan

The effective approach to quantum dynamics allows a reformulation of the Dirac quantization procedure for constrained systems in terms of an infinite-dimensional constrained system…

The Conformal Constraint in Canonical Quantum Gravity

Gerard 't Hooft

Perturbative canonical quantum gravity is considered, when coupled to a renormalizable model for matter fields. It is proposed that the functional integral over the dilaton field s…

Probing the small distance structure of canonical quantum gravity using the conformal group

Gerard 't Hooft

In canonical quantum gravity, the formal functional integral includes an integration over the local conformal factor, and we propose to perform the functional integral over this fa…

An effective approach to the problem of time

Martin Bojowald, Philipp A Hoehn, Artur Tsobanjan

A practical way to deal with the problem of time in quantum cosmology and quantum gravity is proposed. The main tool is effective equations, which mainly restrict explicit consider…

Comment on `Hawking radiation from fluctuating black holes'

Igor Khavkine

Takahashi & Soda (2010 Class. Quantum Grav. v27 p175008, arXiv:1005.0286) have recently considered the effect (at lowest non-trivial order) of dynamical, quantized gravitational fl…

Palatini formulation of modified gravity with a nonminimal curvature-matter coupling

Tiberiu Harko, Tomi S. Koivisto, Francisco S. N. Lobo

We derive the field equations and the equations of motion for massive test particles in modified theories of gravity with an arbitrary coupling between geometry and matter by using…
